AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
145 PM EDT MON JUL 1 2013

.SYNOPSIS...
A LARGE PERSISTENT UPPER LEVEL TROUGH OVER THE REGION WILL SLOWLY
SHIFT WESTWARD AND WEAKEN BY THE MIDDLE OF THE WEEK. UNSETTLED
WEATHER WILL CONTINUE...WITH DEVELOPMENT OF SHOWERS AND
THUNDERSTORMS FOCUSED PRIMARILY DURING THE AFTERNOON AND EVENING
HOURS EACH DAY. TEMPERATURES WILL RISE GRADUALLY THROUGH THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A BAND OF SHOWERS AND THUNDERSTORMS IS SLOWLY PIVOTING UP ACROSS
NORTHWEST PORTIONS OF OUR FA THIS MORNING. THERE DOES APPEAR TO BE
A LITTLE MORE MOVEMENT WITH THESE STORMS COMPARED TO WHAT WE SAW
YESTERDAY...BUT WILL STILL HAVE TO KEEP AN EYE ON POTENTIAL
FLOODING AS THIS IS MOVING ACROSS A FEW OF THE AREAS THAT RECEIVED
SIGNIFICANT LOCALIZED RAINFALL YESTERDAY. OTHERWISE...SHORT WAVE
ENERGY ROTATING AROUND THE MAIN UPPER LOW OVER THE LOWER OHIO
VALLEY SHOULD AID IN DIURNALLY ENHANCED THUNDERSTORM DEVELOPMENT
THIS AFTERNOON. LOCALLY HEAVY RAINFALL WILL REMAIN THE PRIMARY
CONCERN HEADING INTO THIS AFTERNOON BUT SHEAR VALUES ARE A LITTLE
HIGHER TODAY...ESPECIALLY ACROSS OUR EASTERN AREAS. THIS COULD
SUPPORT SOME MARGINALLY SEVERE HAIL/WIND WITH A FEW OF THE STORMS
LATER TODAY. EXPECT HIGHS THIS AFTERNOON IN THE UPPER 70S TO LOWER 80S.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
NUMERICAL MODEL SOLNS GENERALLY SIMILAR WITH ELONGATED UPPER LEVEL
LOW OVER LOWER OH VLY RETROGRADING WEST INTO IL TUESDAY.

SFC LOW AND ASSOCIATED TROF AXIS TO PIVOT NORTH THRU ILNS FA
TONIGHT. WILL BEGIN THE PERIOD WITH THE HIGHEST POPS IN LKLY
CATEGORY ACRS THE SOUTH AND THEN ROTATE THESE POPS NORTHWEST AND
SHOW A DIMINISHING TREND TO CHC CATEGORY.

SFC LOW/TROF AXIS TO SET UP ACRS WESTERN FA TUESDAY WITH AFTN BLYR
CAPES APPROACHING 1000 J/KG. WILL RAMP AFTN POPS UP TO LKLY ACRS
THE WEST WHERE SFC TROF AXIS WILL BE ORIENTED TO CHANCE ACRS THE
SOUTHEAST. TUESDAYS HIGHS WILL CONTINUE TO BE BELOW NORMAL RANGING FROM
THE MID/UPR 70S NW TO THE LOWER 80S SE.

WILL ALLOW POPS TO DIURNALLY DIMINISH TUESDAY NIGHT PER OBSERVATION
THE PAST SEVERAL NIGHTS DUE TO LOSS OF INSTBY.

WILL INCREASE POPS WEDNESDAY BUT LIMIT MAX TO HIGH CHANCE CATEGORY.
WILL CARRY BEST POPS ACRS THE EAST. HIGHS ON WEDNESDAY EXPECTED TO
BE A LTL CLOSER TO NORMAL...FROM UPPER 70S TO THE LOWER 80S.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
HIGHLY AMPLIFIED UPPER PATTERN WILL GRADUALLY CHANGE THROUGH THE
PERIOD AS THE TROUGH IN THE MIDDLE PART OF THE COUNTRY WEAKENS AS
THE HIGH BUILDS WEST FROM THE ATLANTIC COAST. THIS PATTERN WILL
RESULT IN PLENTIFUL MOISTURE ACROSS THE REGION. AND AS DISTURBANCES
ROTATE AROUND THE PERIPHERY OF THE UPPER HIGH THERE WILL BE
CONTINUED CHANCES OF CONVECTION. BETTER COVERAGE WILL BE FAVORED IN
THE AFTERNOON AND EVENING BUT STORMS AT OTHER TIMES OF THE DAY
CANNOT BE RULED OUT. TEMPERATURES WILL INCREASE SLIGHTLY WITH TIME.
THERE IS SOME POTENTIAL THAT THE UPPER RIDGE AXIS COULD END UP A
LITTLE FURTHER NORTH BY THE WEEKEND. AND IF THAT WERE TO OCCUR THEN
THE CHANCE OF RAIN WOULD DECREASE AND TEMPERATURES WOULD BE WARMER.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
AIRMASS HAS DESTABILIZED ACROSS THE AREA THIS AFTERNOON AND THIS
IS ALLOWING FOR ISOLATED TO SCATTERED THUNDERSTORM DEVELOPMENT.
EXPECT THIS TO BECOME MORE WIDESPREAD AS WE PROGRESS THROUGH THE
AFTERNOON...ESPECIALLY ACROSS SOUTHWEST PORTIONS OF OUR FA AS
SHORT WAVE ENERGY PIVOTS UP INTO THE REGION. THUS THE THREAT OF
THUNDERSTORMS WILL CONTINUE ON AND OFF AT THE TAF SITES THROUGH
THIS AFTERNOON AND INTO THIS EVENING. MVFR TO OCCASIONALLY IFR
CIGS AND VSBYS WILL BE POSSIBLE WITHIN ANY OF THESE STORMS. WITH
UPPER LEVEL TROUGH SHIFTING OFF TO THE WEST...THINK MAJORITY OF
ACTIVITY WILL TAPER OFF OVERNIGHT. WE COULD ONCE AGAIN SEE SOME
BR/STRATUS DEVELOPMENT LATER TONIGHT INTO TUESDAY MORNING...BUT
THIS WILL BE SOMEWHAT DEPENDENT ON HOW MUCH PCPN WE END OF WITH
THROUGH THIS AFTERNOON. EXPECT MORE OF THE SAME FOR TUESDAY...WITH
SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING DURING THE LATE
MORNING/EARLY AFTERNOON.

OUTLOOK...THUNDERSTORMS POSSIBLE THROUGH WEDNESDAY.
